Hubungan Metode dan Konsistensi Kontrasepsi dengan Kehamilan Tidak Diinginkan pada Wanita Usia Subur di Indonesia (Analisis Data SDKI 2017)

Abstract

Unwanted pregnancies (UP) are a significant issue contributing to overpopulation problems in Indonesia. This study aims to analyze the relationship between contraceptive methods and their consistency with the occurrence of UP in women of reproductive age, using Poisson regression analysis. The study population includes women aged 15-49 years who have given birth in the last year before the 2017 SDKI survey was conducted. The initial sample consisted of 3.728 women, but after complex estimation, the final sample used was 3.528 women. This cross-sectional study employed bivariate and multivariate analyses to calculate the Prevalence Ratio (PR). The findings revealed that 82,4% of women had experienced a desired pregnancy, while 17.6% had experienced an unwanted pregnancy (95% CI = 16,1% to 19,1%). This indicates that nearly 1 in 5 women experience unwanted pregnancies. The study also found a significant association between contraceptive use and unwanted pregnancies, with p-value of 0,001. Women using hormonal (PR = 0,505), natural (PR = 0,526), or no contraception (PR=0,514) had a lower risk of experiencing UP compared to those using long-acting contraception. Women using barrier methods showed a PR of 0.612 with a p-value of 0.069, indicating no significant result. Additionally, women using contraception for more than 6 months had a lower risk (PR = 0,777, p = 0,017) of experiencing UP compared to those using contraception for less than 6 months. Age and parity were identified as controlling variables in the relationship between contraceptive methods, consistency, and UP occurrence. This study concludes that choosing the appropriate contraceptive method and consistent use can help reduce the incidence of UP, thereby contributing to controlling overpopulation in Indonesia. Contraceptive education and improving access to reproductive health services are essential to support sustainable UP reduction.
